Today I performed some trigger experiments with the SIG P320 X5 I'm testing. This is information which will be in my review next week, but many folks getting their X5's tomorrow will want to know this. Many of you will recall the trigger pull weight measurement I posted on Friday for the stock P320 X5 - 5lbs 12.7 oz. I had a new Grayguns PELT trigger kit handy and wanted to see what different combinations of Grayguns components would yield in results. The first thing I did was swap out the stock X5 trigger for the PELT curved trigger - this yielded very little difference from the stock measurement - 5lbs.13.4oz. Next I tried the PELT trigger spring with the Grayguns curved trigger - this yielded a reduction in pull weight - 5lbs. 4oz. Finally, I used the stock X5 flat trigger with the PELT trigger spring. This yielded the most optimal results - 4lbs.12.1oz.
